Familiarity with GM circle track 525 engine?

They are a little tricky to find on the web so figured i'd save you some time:
Thompson automotive 313-538-0044

I found them, thanks. Seems like a good deal - carb, n/a, complete (dyno'd, carb, controller, etc...), head/cam LS7 with 600-650ish hp, a hair under 13,000. Hmmm, me likey that a lot :drunk:
